Central News (West) and CITV in-vision continuity shared a single studio space at Gas Street for a period circa late-1990s/early-2000s. The respective sets were opposite each other. This was an era when the main 6pm CNW was generally the only one to use the main set, with short bulletins coming from a small CSO virtual set instead (wherever that was located).
CNW decamped to the Gas Street foyer for several weeks in the summer of 2005 whilst a dividing wall was built to turn it into two separate studios. It wasn't an equal 50:50 division of the space. CN West got the slightly smaller of the two studios afterwards, with CN East being moved from Nottingham to the larger of the two Brum studios. CITV continuity therefore became out-of-vision, and ultimately also moved to being done in Manchester/Salford.
Network programmes (e.g. Bullseye) had come from the Nottingham studio complex (Lenton Lane) ever since the Brum operation had downscaled from the big Broad Street complex to the Gas Street potting shed. By the time that the reboot-of-a-reboot of Crossroads was axed, it was the only remaining Central network studio production. The site was then sold to the University of Nottingham, and the CNE newsroom moved to an office facility on some far-flung Nottingham business park or similar.
Since the 2009 changes (with both sub-regions now sharing the same studio/set/presenters/crew, pre-recording and all), it is the former "East" studio in Brum being used. The smaller former "West" studio has since been used for non-television purposes by non-ITV tenants of the 22 Gas Street building.
What a load of b_llo__s!
